16-Dec-2007 -- The confluence is found in the middle of a large shallow lagoon on a wetland area at 12 km from Helvecia.

We approached the Confluence point by land until we where at 6km. From there we used a zodiac boat and navigated until the lagoon. On the way we had to get out of the boat and walk in parts of very low depth.

We had a windy day which made it hard to get all zeroes; at the end, one of us had to get into the water to mark the location with a pole.
